A LIST OF THE BIRDS OF THE ISLAND OF BUTE 143 



WHIMBREL (IV. borealis). A few are seen on passage in spring 

 and autumn. The most I have seen in one flock was seventeen at 

 St. Ninian's Bay on 28th April. 



COMMON TERN (Sterna flumatilis). Common. In some seasons 

 many nest in the Kyles of Bute. 



ARCTIC TERN (Sterna macrura}. Occasionally seen, but much 

 less common than the former species. 



BLACK-HEADED GULL (Larus ridibundus). Fairly numerous in 

 winter, and a few remain in summer. 



COMMON GULL (L. canus). Fairly common. A few pairs nest 

 on the island and on Inchmarnock. So far as I know, this is the 

 only Gull that nests in Bute. 



HERRING GULL (L. argentatus). Common at all seasons. 

 LESSER BLACK-BACKED GULL (L. fuscus). Common, unless in 

 mid-winter, when few, if any, are to be seen. 



GREAT BLACK-BACKED GULL (L. marinits). A few pairs of this 

 fine species are to be seen, especially in winter. 



ICELAND GULL (L. kucopterus). An immature example of this 

 species was exhibited in the flesh, at a meeting of the Andersonian 

 Naturalists' Society, on i2th January 1900. It had been received 

 that day by M'Culloch and Son, taxidermists, Glasgow, from Port 

 Bannatyne, where its presence was known for about three weeks 

 ere it fell a victim to the gun. 



KITTIWAKE GULL (Rissa tridactyla). Common at all seasons. 



POMATORHINE SKUA (Stercorariiis pomatorhinus). Mr. A. 

 M'Cunn, Shipbuilder, Greenock, obtained five, and saw three others, 

 in Kilchattan Bay in October 1879 ("Proceedings of Nat. Hist. 

 Soc. of Glasgow," vol. iv. p. 274). 



RAZORBILL (Alca torda). Common in summer all round the 

 island. 



GUILLEMOT (Uria troile). Like the Razorbill, common in 

 summer, and numerous parties are to be seen in winter too. 



BLACK GUILLEMOT (U. grylle). Mr. Bodin, Port Bannatyne, 

 informed me that this species is sometimes shot in autumn. 



PUFFIN (Fratercula arctica). Common in summer off the south 

 and west of the island. 



GREAT NORTHERN DIVER (Colymbus gladalis), RED-THROATED 

 DIVER (C. septentrionalis). Divers are fairly common just off 

 the shore in winter. Mr. Evans was able to identify both _ of 

 these species during his visit. I have seen a Red-throated Diver off 

 the west coast as late as the middle of May. 



GREAT CRESTED GREBE (Podicipes cristatus). A single example 

 is recorded by Mr. Evans.
